How to Polish Glass Edges with a Dremel – Full Informative Guide

Are you wondering how to give your made-from-home glass bottle that polished finish? The term Dremel is usually interchanged with rotary tools. Bosch is a company that makes rotary tools that they call Dremel. Dremel tools come with different attachments, each with unique functionalities. Dremel has been sampled and picked as a preferred tool type among the methods and tools used for glass edge polishing. Here are tips and step-to-step guides on how to polish glass edges with a Dremel.

How to polish glass edges with a Dremel

After assembling all the tools, follow this step on how to polish the glass edges with a Dremel. Before we begin, the process uses a rotary Dremel either with the buffing pad or the polishing bits. Both buffing pads and polishing bits are accessories that can be attached to the front end of the Dremel and put in place with a special nut (Keyless chuck). The mechanism of the keyless chuck enhances faster switching between drill bits and accessories during the entire project. This step-by-step guide will focus on how to polish glass edges with a Dremel while using the bits. (Not the buffing pads). 

Tools you will need

  • Dremel rotary tool
  • Diamond, tungsten carbide, or silicon carbide tips
  • Plastic tub or towel
  • Water
  • Safety glasses
  • Glass
  • Clean rags or paper towels

Step 1

After you have assembled everything and prepared your workspace, please pick up the Dremel, attach a diamond bit correctly, and ensure it has been fitted to the furthest end. Use the chuck to hold it safely onto the rotary tool. You can choose to mount your Dremel tool or have it on hand, depending on the type of glass edge you are working on.

Step 2

Safety should be exercised at all times. Put on heavy-duty gloves and safety goggles. Assemble the glass material in place, ensuring that the surface that must be polished is in an ideal position for the rotary. The glass can be placed on a soft cloth or carefully clamped down onto the working table. Throughout the process, water or a commercial lubricant should be used (wet sanding). 

Step 3

Hold the Dremel onto the dominant hand, and wet the glass surface upon which to sand. This position is preferred if the glass project can be held onto the hand while working. Alternatively, placing it down onto a soft piece of cloth is also ideal.

Step 4

Power the Dremel and move it carefully and steadily to the inner parts of the glass edge. With the bit in contact with the glass edge, run the rotary appliance, following along the glass edge. Maintain less pressure while running the bit to avoid glass breakage. Pose for a while and sprinkle water to prevent the glass dust and also help to maintain a smooth grind. To attain a smoother finish, have some patience, and spend at least 3 minutes on this step.

Step 5

After sanding the inner part of the glass, move to the top and outer parts of the edge. The glass edge is ideal when it has a rounder edge. To achieve a rounder age, move from the outer side of the edge towards the inner parts of the glass edge. This technique can easily be performed when the glass is slightly angled. (Picture a movement that occurs when someone rides a wave in the ocean.) Three minutes is ideal for this process.

Step 6

This step is the actual polishing process. Unfasten the diamond bit and replace it with a fine-grit bit. When switching between bits, ensure that the Dremel has been turned off. Repeat the process similar to step 5. Continue polishing until you achieve the desired finish.

Step 7

Use a clean cloth to remove dust residues or grit debris from the glass. Similarly, wash the glass with water and regular dish soap. Do not forget to clean and dry wipe the Dremel tool as well. 

Benefits of polishing glass edges with a Dremel

Speed and efficiency

Dremels are high-energy-efficient tools. It can shift power depending on the material being sanded. They also offer higher RMPS of up to 35000 (4300 series). They are quick to use and save a ton of time. A good polish can easily be achieved in under 5 minutes. When dealing with intricate glass edges, using a Dremel is much quicker than when sanding glass edges by hand.

Keyless chuck

Dremel comes with a quick-change mechanism known as a keyless chuck. They do not require additional keys to open or close them. This mechanism eases the polishing process. You are able to shift between drill bits and grits with a lot of ease while working on the glass edge.

Variety of attachments

Dremel tools come with a variety of attachment bits to help you have the desired finish without having to source for other accessory tools elsewhere. A Dremel glass polishing kit has a variety of these attachments. It has bits for not only polishing glass but also engraving and cutting.


The Dremel possesses more extended longevity. Depending on the frequency of usage, they can last close to a minimum of 3 years and up to 6 years. You do not have to worry about replacing your Dremel tool anytime soon.


The Dremel tool offers a smooth learning curve. A beginner with no skills can quickly achieve a close-to-professional glass polish with a few basics. Its form factor enhances a comfortable grip (Pencil-like Grip) with maximum control.

Mandrel compatibility

Because of the rotary tool mandrel, the EZ lock mandrel, and the screw mandrel, the Dremel tool has a wide range of compatibility. This enables various polishing bits and grits for advanced glass edge polishing. This compatibility is also advantageous because it can be used by a professional, a beginner, and a DIY enthusiast.

Light source

Some Dremel models, such as the Dremel 4300, include an illumination light that can be rotated at various angles. It’s ideal for working on detailed glass edging where an additional light source is helpful.

How to polish glass edges with a dremel: Tips

  • A soft touch is the best for this tool as applying pressure can stop the device from rotating and breaking or damaging the glass edge. This is also true when using sandpaper for glass polishing.
  • Using the right bits or grits on each polishing process tip will increase the chances of achieving a professional finish.
  • Use water or commercial lubricant while polishing glass to avoid breaking the glass and also to reduce the spread of glass particles while working on your project.
  • To achieve the best results, work with the right Dremel attachments depending on the requirements of your projects.
  • While polishing glass, put on the necessary safety equipment such as eye goggles, a breathable mask, and gloves. The polishing process tends to have glass particles coming from the grinding process.
  • Follow the electric regulation measures while handling Dremel to increase the longevity of your tool and avoid electricity risk hazards.
  • Before you begin polishing, ensure that the bits and grits on the Dremel have been tightly put in place, thus enabling a reduced vibration.
  • Be careful of the spinning speed of the Dremel. Always start low and then advance to higher speeds as you move on. 
  • When polishing glass with Dremel, turn off the Dremel and unplug it from the socket when switching between attachments (bits, grits, pads)

Frequently Asked Question

Can you polish the edges of tempered glass?

Yes. Tempered or toughened glass can be polished using a diamond bit grit. Silicon carbide can also be used. Wear a breathable mask and eye goggles while working with tempered glass. Do not rush. Exercise caution with even and steady movement. Add water to cool down the tempered glass.

How do you grind glass edges?

Use specialized bit accessories that work well with glass. A diamond bit is a good example. To ensure safety, wet the glass during grinding.

Can you polish it with a Dremel?

Dremel offers a wide range of attachments that can polish just about any surface. The key is choosing the right drill bits for each texture and knowing how to use the Dremel tool. 

How do you polish chrome with a Dremel?

Turn on the Dremel tool and set it to low and medium settings (between 12000 and 24000 RPMs).  Install a fine grit buffing pad or attachment that can reach into difficult-to-polish areas. Start on a low toque before moving to a higher toque. Buff the chrome by gently pushing the buffing pad on it. Add additional drops of chrome cleaner for lubrication.


Glass edge polishing is done to eliminate the sharp edges that may cause harm and also achieve a good-polished finish. The speed of the Dremel and the type of attachments used will always affect the polished finish of your glass. It’s high time you put the know-how on how to polish glass edges with a Dremel into action. Whether you plan on removing dents from your glass, polishing your chrome, or doing a DIY project, a Dremel tool has you covered.
